Green juice (1 piece)

Choose a mostly-vegetable juice: prioritize leafy greens, cucumber, celery, parsley, and lemon; limit or omit fruit, especially bananas, mango, pineapple, and large amounts of apple.

Keep the serving small (about 120–180 mL) and dilute it with water or ice to reduce the carbohydrate load at one time.

Have the juice with a protein- and fat-containing snack, such as plain Greek yogurt, a boiled egg, avocado, or a small handful of almonds.

Add fiber when possible: blend rather than juice, or stir in chia seeds or ground flaxseed after juicing.

Avoid drinking it on an empty stomach; have it with or after a balanced meal instead.

Take a gentle 10–20 minute walk after drinking it and avoid pairing it with other sweet drinks or refined carbohydrates.
